Question
Two jobs idJOB1 and idJOB2,if you set idJOB1-ENDED-OK as an IN condition for idJOB2,then what does it mean?
A. idJOB2 will start execute only after the compleation of idJOB1
B. both the jobs will start execute at the same time
C. idJOB2 will start execute ,even at the unsucessful compleation of idJOB1
D. Both B & C
Answer
A. idJOB2 will start execute only after the compleation of idJOB1
Explanation
When you set idJOB1-ENDED-OK as an IN condition for idJOB2 in IBM mainframe job control, it means that idJOB2 will only start executing after the successful completion of idJOB1.
In more detail, specifying idJOB1-ENDED-OK as an input condition makes idJOB2 dependent on idJOB1 finishing with a return code of zero, indicating it ended normally without any errors. idJOB2 will be held in a wait state until idJOB1 completes successfully. If idJOB1 abends or has a non-zero return code, idJOB2 will not be released for execution.
This allows setting up job dependencies and sequences to ensure prerequisite steps complete properly before subsequent jobs run. It does not mean the jobs start simultaneously or that idJOB2 will execute if idJOB1 ends unsuccessfully.
Therefore, the correct answer is:
A. idJOB2 will start execute only after the compleation of idJOB1
